Abstract

Die Erfindung betrifft ein Verfahren zum Einspeisen elektrischer Leistung in ein eine Netzspannung mit einer Netzfrequenz aufweisendes elektrisches Versorgungsnetz (120) mittels eines umrichterbasierten Erzeugers (100, 112), insbesondere mittels eines Windenergiesystems (100, 112), umfassend die Schritte: Schätzen eines Umrichteranteils eines Netzabschnitts des elektrischen Versorgungsnetzes (120), wobei der Umrichteranteil ein Verhältnis mittels Umrichter eingespeister Leistung zu insgesamt eingespeister Leistung bezeichnet, Einspeisen elektrischer Leistung in das elektrische Versorgungsnetz (120) in einem Normalmodus in Abhängigkeit vom geschätzten Umrichteranteil, Aktivieren eines ersten Stützmodus in Abhängigkeit vom geschätzten Umrichteranteil gemäß einer ersten Aktivierungsbedingung, Aktivieren eines zweiten Stützmodus in Abhängigkeit vom geschätzten Umrichteranteil gemäß einer zweiten Aktivierungsbedingung, die zur ersten Aktivierungsbedingung verschieden ist. Die Erfindung ist dadurch gekennzeichnet, dass im ersten Stützmodus eine schnelle Leistungsreduktion erfolgt.The invention relates to a method for feeding electrical power into an electrical supply network (120) having a network voltage with a network frequency by means of a converter-based generator (100, 112), in particular by means of a wind energy system (100, 112), comprising the steps: estimating a converter component of a Network section of the electrical supply network (120), wherein the converter share denotes a ratio of power fed in by means of the converter to the total power fed in, feeding electrical power into the electrical supply network (120) in a normal mode depending on the estimated converter share, activating a first support mode depending on the estimated converter share according to a first activation condition, activating a second support mode depending on the estimated converter share according to a second activation condition that is different from the first activation condition. The invention is characterized in that a rapid power reduction occurs in the first support mode.
